Azure Arc: Managing Hybrid Resources

Most organisations operate in a hybrid environment: some workloads run in Azure, others on on-premises servers, and some on other cloud providers. Managing these disparate environments with separate tools creates operational silos — different policies, different monitoring, different access controls. Azure Arc solves this by extending the Azure management plane to any infrastructure, letting you manage on-premises and multi-cloud resources using the same Azure portal, CLI, policies, and RBAC you use for Azure-native resources.

Azure Arc is a set of technologies that projects non-Azure resources into Azure Resource Manager (ARM) so they appear as Azure resources with resource IDs. Currently, Arc supports: Servers (Windows/Linux VMs on-premises or other clouds), Kubernetes clusters (any CNCF-conformant Kubernetes), SQL Server instances, Azure data services (SQL Managed Instance and PostgreSQL on Arc), and VMware vSphere and Azure Stack HCI virtual machines.
